i shoot a k-hornet in a 21in. contender barrel,i use the 35gr. v-maxes, and they are very accurate, and explosive, out to 200yds. not real loud, i guess? not at all like my 22-250AI.
i have only used hand load,s for mine. but iv,e seen hornady 35grainers in factory ammo, that said 3100fps. mine do just under 3200. they shoot real flat! i have shot a bunch of groundhogs with mine, the longest being 230yds. i was shocked to connect on that one!
dont get too picky about match grade accuracy, mine shoots about three quarters of an inch at 100 yards, thats 1.5 inches at 200.(give or take) if i do my part, i own anything inside 200yds.
i also have guns that i shoot in matches that will avarage quarter inch groups.(diffrent ball game!)
i have heard of bad accuracy from other,s, but always from a hornet chamber, not (k-hornet) like mine.
the 22-hornet will kill fox, and coyote,s but on the coyote,s, pick your shots! it,s able, but has no power to spare! so if you shoot the factory stuff at game. pay a little more for modern bullets.
good luck.
